Exception caught in Forward Dynamics
Posted: Sat May 15, 2021 7:04 am
Hi,
i added 6 DoF to patellofemoral joint in Schmitz Model (6 coordinates and 6 spatial transforms).
Exception was caught in Forward Dynamics:
Integrator initialization failed apparently because:
SimTK Exception thrown at SmallMatrixMixed.h:879:
Error detected by Simbody method lapackInverse(Mat<>): Matrix is singular so can't be inverted (Lapack getrf info=3).
(Required condition 'info==0' was not met.)
What can cause this problem?
Regards,
Alexandra
